HOT-WATER-HEATER GAS REGULATOR! Application filed January 18, 1922.

To aZZ whom it may concern:

Be it known that I, BENJAMIN A. HAW- KINS, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Hotater- Heater Gas Regulators, of which the following is a specification.

This invention relates to certain new and useful improvements in hot water heater gas regulators and the primary object thereof is to provide improved means instantly re sponsive to the water pressure so that upon opening of the faucet to draw off water the decreased pressure will effect opening of the gas controlling valve to thereby cause lighting of the gas for the heater.

A further object of the invention is to provide a regulator which is positive in operation, simple and economical in construction and of compact and ready assemblage and possessed of a minimum of parts not subject to easy derangement.

Further and other objects-will be later set forth and manifested in the course of the following description.

In the drawings:

Figure 1, is a vertical sectional view,

Figure 2, is a fragmentary like view showing the gas valve in open position, and Figure 3 is a view similar to Figure 2, showing the position of the parts under normal water pressure.

In proceeding in accordance with the present invention, a casing 1 is employed having a diaphragm 2 therein, the casing being connected by a pipe 3 to the water supply. A second casing 4 is connected by a coupling 5 to the casing 1 and has a sliding rod 6 therein, the latter connected at its lower end to the diaphragm. A link 7 is pivoted at one end at 8 within the casing 4 and carries a pivoted weight 7 at its opposite end, an intermediate part of the link being extended through a slot 9 formed in the rod 6. A second sliding rod 10 is mounted in the casing 4: and is suitably connected to a gas controlling valve 11 mounted in the gas line 12 the latter leading to the usual gas burner, not shown. A link 13 is pivoted at 14 within casing 4 and has an intermediate part passed through a slot 15 provided therefor in the rod 10. A curved or L-shaped actuating member 16 is slidably pivoted at 17 to the free end of the link 13 by virtue Serial No. 530,213.

of slot 13 in'link 13, and has its opposite end pivoted at 18 to the casing. A cam member 19 is ri idly secured to the actuating member 16 in ,a position to engage the free end of the link 7 In operation,:the parts in the position of Figure 1, are depicted at rest, no water pressure whatever being in the waterline.

hen water is admitted to the casing 1, the water acts on :thediaphragm 2, raisingrod 6 and thereby link 7 and the weight 7,,the free end of the link 7 engaging the cam member 19' in which position of the parts, under normal water pressure, the gas valve 11 is closed. "When a :faucet is opened and the water pressure is .diminished accord ingly, the diaphragm moves downwardly and with it rod 6 and link 7, the latter wiping against the cam to gradually open the gas valve until the link 7 reaches the cam edge 20 of member 19 and thereby causing member 16 to move upwardly and therewith link 13 and rod 10 efieoting complete opening of the gas valve 11 to permit of full flow of the gas to the burner. When in the position of Figure 2, i. e., under initial reduced water pressure, the outer end of the link 7 is above the effective part 20 of the cam member or the cam proper, so that when link 7 drops, the outer end of same wipes against the cam edge 20 to thereby impart an upward movement to the member 16 and corresponding movement of the link 13 and thereby of rod 10 and valve 11. Should the water pressure in'the pipe 3 be reduced to such a point as to cause the lever 7 and weight 7 to drop into the position shown in Figure l the gas valve 11 will be closed and will remain closed until the water pressure lifts the lever 7 and weight 7 to the position shown in Figure 2, thenthe gas valve 11 will be opened permitting the flow of gas which will be lighted by the pilot light forming part of the burner to the well known form of water heaters.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a gas regulator, a casing, a sliding rod therein, a pivoted weighted link in the casing, a diaphragm connected to the rod and responsive to the water pressure, a second sliding rod in the casing having a gas supply controlling valve connected thereto, a pivoted link connected to the second-rod,

an actuating member pivoted to the casing and pivotally and slidably connected to the second. link, and a cam rigid on said memher and engageable With the outer end of the first named link.

2. In a gas regulator, a sliding rod, a water pressure responsive diaphragm connected to the rod, a pivoted link carrying a Weight, operated by the rod, a second sliding rod having a gas supply controlling valve connected thereto, a pivoted link connected to the second rod, and cam means connected to the second linkand operated by the first link. to actuate the second rod.

3. In a gas regulator, a Water pressure responsive member, a gas supply controlling valve, a pivoted link connected to the mem ber, a pivoted link mounted independent of the first link and having connection With the valve, and cam means connected to the second link and operated by the first link to operate the valve.

4. In a gas regulator, a Water pressure responsive member, a gas controlling mem- 25 ber, a pivoted link coacting With each member at points between the ends of the respective links, the opposite ends of the links being spaced apart, means to tension one link to normally hold same spaced from the other link, and a cam. having connection With the other link and engageable by said opposite end of the tensioned link so as to effect operation of the gas controlling member upon predetermined movement of the Water responsive member.

5. In a gas regulator, a Water pressure responsive member, a gas controlling member, a pivoted device coacting With each of said members, means to tension one of said devices, and cam means having connection with the other device and engageable With and disengageable from a part of the ten-- sioned device so as to effect operation of the gas controlling member upon predetermined movement of the Water responsive member.

In testimony whereof I have signed my name to this specification 1n the presence of tWo subscribing Witnesses.
